[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-5 The present invention provides an adjustable ceiling mount for a projector, comprising a connecting plate 1 and a movable base 2.

[0027] Reference Figures 1-4 As shown, a movable base 2 is provided below the connecting plate 1. A lifting structure 3 is evenly installed on the top of the movable base 2. The lifting structure 3 includes a fixed column 301 installed on the top of the movable base 2. A connecting rod 302 is provided inside the fixed column 301. An internal groove 303 is opened at the bottom of the connecting rod 302. A snap-fit ​​rod 304 is provided inside the internal groove 303. A return spring 305 is fixed on one side of the snap-fit ​​rod 304. Through holes 306 are evenly opened on both sides of the fixed column 301. The fixed columns 301 are symmetrically distributed on the top of the movable base 2. The connecting rod 302 is slidably connected inside the fixed column 301. One side of the snap-fit ​​rod 304 is semi-circular. The through holes 306 are evenly distributed on both sides of the fixed column 301. The snap-fit ​​rod 304 is set inside the through hole 306. The snap-fit ​​rod 304 and the fixed column 301 form a snap-fit ​​structure through the through hole 306.

[0028] During the operation of the projector, it needs to be installed on the ceiling. In order to ensure that the projector illuminates the appropriate position, the height of the movable base 2 needs to be adjusted. A lifting structure 3 is provided, which connects the connecting plate 1 and the lifting structure 3 through a fixed column 301 and a connecting rod 302. The connecting rod 302 slides inside the fixed column 301 and is fixed in position by a locking structure formed by a locking rod 304 and a through hole 306. Pressing the locking rod 304 moves it away from the through hole 306 and into the built-in groove 303, thereby releasing the positioning and allowing the connecting rod 302 to slide and adjust inside the fixed column 301. This changes the distance between the connecting plate 1 and the lifting structure 3, thereby changing the height of the movable base 2 and greatly increasing the practicality of the device.

[0029] Reference Figure 1 , Figure 2 and Figure 5 As shown, mounting blocks 4 are evenly fixed on the outer side of the connecting plate 1, and an adjustment structure 5 is provided above the movable seat 2. The adjustment structure 5 includes a mounting plate 501 set above the movable seat 2. Threaded holes 502 are evenly opened inside the mounting plate 501, and mounting bolts 503 are provided inside each of the threaded holes 502. Fixing blocks 504 are evenly fixed at the bottom end of the mounting plate 501. Electric push rods 505 are evenly installed at the top end of the movable seat 2 below the mounting plate 501. The threaded holes 502 are evenly distributed inside the mounting plate 501, and the fixing blocks 504 are evenly distributed at the bottom end of the mounting plate 501. The top of the electric push rod 505 is located inside the fixing block 504, and the electric push rod 505 is rotatably connected to the fixing block 504.

[0030] During the illumination process using a projector, the illumination angle needs to be adjusted. Therefore, by setting an adjustment structure 5, the projector is installed on the top of the mounting plate 501 by mounting bolts 503, so that it is not easy to shift its position during use. The bottom end of the mounting plate 501 is evenly fixed with fixing blocks 504, which are rotatably connected to the electric push rod 505 fixed on the top of the movable base 2. Activating the electric push rod 505 makes it easy to adjust the tilt angle of the mounting plate 501, which makes it easy to adjust the illumination angle of the projector, thereby greatly increasing the practicality of the device.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
